City Department of Education officials are dramatically slashing school-construction spending and blaming impending overcrowding on the state — even as the city plans to nearly triple funding for classroom technology.

In a late-afternoon release yesterday of revisions to their 399-page, five-year school-construction plan, DOE officials said they’re being forced to cut new seat production through 2014 from roughly 30,000 to 14,500.

They blamed what they’re calling a 48 percent cut in building aid from the state for new capital projects.
